辽宁省苇子峪地区水系沉积物地球化学特征及金多金属找矿远景预测

Geochemistry of Stream Sediment and Metallogenic Prognosis of Gold-polymetallic Ore Deposits in Weiziyu Area,Liaoning Province

为更好地指导区域找矿工作,缩小找矿范围,在辽宁省苇子峪地区开展1∶5万水系沉积物测量的基础上,对化验结果进行了分析,结合研究区成矿地质条件共圈定出18处综合异常。通过对Hs-10综合异常进行查证,发现3条金多金属矿(化)体,结合区内的矿产分布特征、化探异常特征、航磁异常特征,共圈定3处找矿远景区:东岔Mo-Cu-Pb-Zn-Au多金属找矿远景区、棒槌砬子Au-Fe多金属找矿远景区、金斗Au-Fe多金属找矿远景区。

In order to provide better guidance for the ore prospecting works in the region and narrow down the prospecting scope,a total of 18 comprehensive anomalies were identified in Liaoning province,which were on the basis of the stream sediment survey in 1∶50000 scale of the Weiziyu area,test analysis results,and the ore-forming geological conditions in the studied area.Three gold polymetallic mineralization bodies were explored based on the investigation of Hs-10 comprehensive anomalies.According to the comprehensive anomaly analyses and investigations,as well as the regional mineralization characteristics of aeromagnetic anomalies and local geological settings,three metallogenic prospects are delineated.They are the Dongcha Mo-Cu-Pb-Zn-Au metallogenic prospect area,the Bangchuilazi Au-Fe metallogenic prospect area and the Jindou Au-Fe metallogenic prospect area.
